Hello all, I have a Scrub Oak tree in my front yard, and I have St. Augustine underneath it. The grass is very thin and I was told that is because oak trees turn the soil acidic. I had lime put down last year but the grass still looks the same.ello all, I have a Scrub Oak tree in my front yard, and I have St. Augustine underneath it.

Step 1. Plant the oak tree in a location that provides at least eight hours of direct sunlight, good air ventilation and nutrient-rich soil. The soil's nutrients are essential for the tree's development.tep 2. Test your soil's pH levels and match them to the specific oak tree selection. There are several different kinds of oak trees, including the Northern Red, Live, Southern Red, White and Willow, to name a few.
